It can hold up to 21 samples at a time, which makes the testing process highly efficient.

1. The test results are accurate, precise and stable. The system design is optimized to ensure the complete combustion of coal sample, the complete electrolysis of SO 2 and the complete integration of current (charge).

2. The design of the hardware integration signal circuit with high precision and low drift, the single chip microcomputer can carry out the hardware integration in the electrolysis process, which can completely overcome the disadvantage of the software integration easily missing the data, and the integration is complete, which can effectively ensure the accuracy of the measured value.

3. The high temperature furnace is heated by silicon carbide tube, temperature is measured by platinum rhodium-platinum thermocouple, and temperature is controlled by computer.

4. The two-bar sample delivery mechanism significantly improves the stability of sample delivery, while its unique lifting-step push structure effectively prevents sample flipping and jamming.

5. The platinum electrolytic electrode (195mm²) and indicator electrode (77mm²) are widened and thickened, with their areas increased by 30% and 4 times respectively compared to conventional instruments. This provides a larger contact surface, ensuring more precise and complete integration.

6. High degree of automation, automatic heating, constant temperature, cooling; storage and processing of test data.

7. After placing 21 samples at once, the system automatically delivers, tests, dispenses, and discards them, allowing unattended operation. Samples can be added or replaced at any time during the experiment.

8. The system design takes full account of the fatigue resistance of the instrument, especially the components in the high temperature environment. The high temperature furnace adopts the new imported material, which has good heat preservation effect and long service life.

9. The working model and device design minimize the water vapor flowing into the drying tube, and the large capacity drying tube effectively reduces the frequency of the replacement of the desiccant, the labor intensity of the operator and the operating cost.

10. The system uses a stable, maintenance-free air pump that eliminates the need to replace rubber bowls, ensuring a long service life.

11. The airtightness test is convenient, and the operator only needs to gently pull with the finger, and it can be automatically completed;

12. A new electrolytic cell leakage corrosion protection design is introduced to prevent abnormal leakage from causing corrosion to the instrument.

13. It is equipped with a muffler, which is healthy and environmentally friendly.
